How to choose the right aquarium filter?


Choosing the right aquarium filter is the most important step in providing a healthy environment for your fish. The right choice depends on several key factors such as the size of the aquarium, the type and number of fish you keep. To make an informed decision, it is important to assess the needs of your specific ecosystem.
Before you settle on a specific model, consider the following important features:

  • Aquarium size and volume: Each filter has a certain capacity, measured in liters per hour (l/h). A general rule of thumb is that the filter should be able to clean the entire volume of your aquarium at least 3-5 times within one hour.
  • Filtration type: A good filter provides three types of filtration: mechanical (removes large particles), biological (beneficial bacteria break down ammonia and nitrites), and chemical (removes discoloration and odors).
  • Fish type: Some fish, such as goldfish or cichlids, produce more waste and require more powerful filtration. Delicate fish, such as discus, prefer a weaker water flow.
  • Noise level: If the aquarium is located in a bedroom or living room, choosing a silent aquarium filter is essential for your comfort. Modern models are designed to operate extremely quietly.

By considering these guidelines, you will be able to easily navigate the variety and choose the top aquarium filter that fully meets your requirements.

What are the main types of aquarium filters?


Understanding the different types of filters will help you choose the most effective solution for your aquarium. The main types are internal and external (canister) filters, each of which has its own specific advantages. The choice between them depends mainly on the size of the aquarium and your personal preferences for maintenance and aesthetics.
To make it easier for you, here is a brief description of the most common types of filters:

  • Internal filters: These are placed entirely inside the aquarium. They are ideal for smaller aquariums (up to about 100-120 liters). They are compact, easy to install and usually have a more affordable aquarium filter price. They are an excellent choice for beginner aquarists.
  • External filters (Canisters): These filters are placed outside the aquarium, usually in the cabinet below it, with the water circulating through hoses. They offer a much larger volume for filter media and therefore much better biological and mechanical filtration. They are considered the top aquarium filter for larger tanks and for keeping more sensitive fish.
  • Hanging-on-back filters: They are hung on the edge of the aquarium. They combine the advantages of internal and external filters - they are easy to maintain and do not take up space inside the aquarium. They are suitable for medium-sized aquariums.

Each of these filters has its role in aquariums and offers an effective solution for maintaining a clean and healthy aquatic environment.

Why is quality filtration vital?


Quality filtration is absolutely mandatory because it acts as a life-support system in the closed ecosystem of the aquarium. Without an effective filter, toxic substances such as ammonia and nitrites will quickly accumulate to lethal levels. A good aquarium filter is a guarantee of the health and longevity of your aquatic inhabitants.
Think of the filter as the kidneys and lungs of your aquarium. It purifies the water from harmful waste while also saturating it with oxygen. The constant water movement created by the filter prevents the formation of stagnant zones and ensures an even distribution of heat and nutrients. Investing in a quality, reliable and even silent aquarium filter is the best care you can take for your fish, providing them with an environment close to their natural environment.

Frequently Asked Questions

1. How often should I clean my aquarium filter?


The cleaning frequency depends on the type of filter and the workload of the aquarium. Internal filters usually require cleaning the sponges every 2-4 weeks. External filters (canisters) can work effectively for months (2-6 months) without the need for a complete cleaning. It is important to never wash the biological filter media with tap water, but only with aquarium water to preserve the beneficial bacteria.

2. What does filter flow rate (l/h) mean?


The flow rate, measured in liters per hour (l/h), indicates how much water the filter can process in one hour. It is recommended that the filter flow rate be such that the entire volume of the aquarium is turned over at least 3-5 times per hour. For example, for a 100-liter aquarium, a filter with a flow rate of at least 300-500 l/h is suitable.

3. Could the filter be too powerful for my aquarium?


Yes, it is possible. Excessive current can stress some fish species, such as bettas, neons or discus, which come from calmer waters. If you are concerned about the current being too strong, choose a filter with an adjustable flow rate or direct the outlet jet towards the wall of the aquarium to dissipate it.

4. What is the difference in price between different filters?


The price of aquarium filters varies greatly. Internal filters are the most budget-friendly option. Suspended filters are in the middle price range. External canister filters are the most expensive due to their complexity, large capacity and high efficiency, but they offer the best filtration quality in the long run.
